Insight Into

The pion form factor offers insight into the transition from perturbative to nonperturbative quantum chromodynamics (QCD), and is of current experimental interest. Twisted-mass lattice QCD is a method for eliminating unphysical zero modes from Wilson lattice simulations; it also allows for removal of the leading lattice spacing artifacts through a momentum-averaging prescription. In our study of the pion form factor, we performed the first explicit computation with momentum averaging in twisted-mass lattice QCD, and the first use of the GMRES-DR algorithm for twisted fermion matrix inversion.PACS No.: 12.38.Gc

Lattice QCD simulations with a twisted mass term (tmLQCD) offer solutions to problems associated with simulations using Wilson fermions and a standard mass term. A summary of recent results from quenched simulations using tmLQCD at maximal twist for the pion form factor and hadron spectrum is presented.
